Tom Petty, the rocker best known as the frontman of Tom Petty and the Heartbreakers, is dead at 66, CBS News has confirmed.

The legendary musician suffered a full cardiac arrest and was found unconscious and not breathing at his Malibu home Sunday night. He was taken to UCLA Santa Monica Hospital and put on life support, reports TMZ.

Petty rose to fame in the 1970s with his band, Tom Petty, and the Heartbreakers. The group put out several hits, including "American Girl," "Free Fallin'," "Breakdown," "Listen to Her Heart" and more. The band was inducted into the Rock and Roll Hall of Fame in 2002.

Though Petty and his band debuted their first self-titled record in 1976, they continued to perform over the past four decades. Petty played his last show last Monday, performing three sold-out shows at the Hollywood Bowl to conclude their 40th-anniversary tour. The band wrote on their website that the tour included 53 shows in 24 states.

In December, Petty told Rolling Stone that he thought this would be the group's last tour together. He said, "It's very likely we'll keep playing, but will we take on 50 shows in one tour? I don't think so. I'd be lying if I didn't say I was thinking this might be the last big one. We're all on the backside of our sixties. I have a granddaughter now I'd like to see as much as I can. I don't want to spend my life on the road. This tour will take me away for four months. With a little kid, that's a lot of time."

Petty also took part in the 1980s supergroup the Traveling Wilburys with Bob Dylan, George Harrison, Roy Orbison and Jeff Lynne.
